Specification of Letters Patent.

Patented Nov. 21, 1916.

Application filed May 6, 1915. Serial No. 26,439.

To all whom it may concern Be it known that 1, WILLIAM G. BURNs, acitizen of the United States, residing at New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Bagging- Pipes, of which the following is a full, clear,and exact specification.

This invention relates to bagging pipes, which are used for filling bagsby gravity from a large supply.

The invention has particular reference to an apparatus in which the rateof flow from the main supply can be varied according to the nature 'ofthe material, such as coffee, cereals, sugar, and the like, incombination with a return pocket into which any excess from the bags maybe returned and discharged into the next bag.

Apparatus of this character is used, for example, in large groceryhouses, where the bags are first filled and then weighed, and it isfound more convenient to allow a slight excess to flOM into the bag andthen remove this by a scoop until the exact weight remains, the bag thenbeing removed and closed up.

This invention provides an apparatus in which the excess removed fromthe bags can be returned to the main supply in the bin through a smallreturn pocket, and the apparatus is so arranged that the materialreturned to the'bin is discharged into the next bag along withadditional material from the main supply. Thereby, accumu lation ofreturned material in the pocket is prevented, and the entire supply isprotected from the air, dust, etc, and main tained of uniform quality.

The invent-ionlis shown in two forms inthe accompanying drawing, inwhich- Figure -1 is an elevation partly in section of one form, and Fig.2 is a. similar view of the preferred form.

1 represents the lower end of a bin con nected by a pipe to the mainsupply, which may be on an upper floor. The bottom of the bin isinclined at 2 opposite the lower interior wall 3, the opening 4 beingCOIL, trolled by a slide 5. This slide is adjusted through the returnpocket 6 to furnish the desired opening to permit sufiicient flow of thematerial without overflowing the bin. The return pocket 6 is providedwith a cover 7, and the lower end isprovided with a gate 8 consisting ofa slide mounted in suitable guides 9, 10, and having -an operatinghandle 11 and stop shoulder l2. The gate is so arranged that thematerial in the bottom of the return pocket may be discharged beforeadditional material from the bin 1 can be discharged. This isaccomplished in Fig. 1 by reason of having the bin 1 discharge into thepocket 6 above the gate 8. so that the material on the gate 8 will fallthrough into the bag discharge pipe 13 faster" than additional materialpasses through the opening 4. from the main supply.

In Fig. 2, the bottom-of the bin 1 and the bottom of the return pocket 6are both controlled by the gate 14, and are separated by the slide 15,which corresponds to the side In this form,

rial in the pocket will discharge into the bag through pipe 13 beforethe main body of material in the bin 1 can be discharged. In this form,the gate 14 is provided with the stop projection 16 to which areattached on opposite sides the U-shaped handle 17, 18 being a spring andhold it in position. The gate 14 slides on guides 19 between plates 20,21, in a manner similar to the gate'S.

In both forms of the invention it will be I the gate 14 opens by movingto the right, so, that any mate-' to engage the handle 17 observed thatthe main supply can be cut off at any time by closing the slides 5 or15, thus providing a simple gate controlled bin. Also, differentmaterials may be mixed as they are filled into bags by feeding onematerial through the pocket 6 and the other through the bin 1 andcontrolling their proportions by-adjustment of the slides 5 or 15. Thisapparatus is also advantageous for obtaining samples, which, afterexami-. nation can be pocket. tom gate pipes, thus doing aavay withsmall receptacles for receiving excess'material or returned samples.Such receptacles are object tionable because unsanitary and because theyhave to be carried up to the main sup" ply on the floor above to beemptied.

Various modifications and changes may be made in the details andarrangements of the various parts without departing from the scope ofthe. appended claims.

Having thus de cribed my invention. I

V rounding walls surrounding walls and a gate for pocket and saidbin-through said outlet dur- -turn pocket declare that -what I claim asnew and desire to secure by Letters Patent, is

1. The combination with a bin, of a return pocket therefor comprisin areceptacle with ownwardly opening outiet, common to said bin and saidpocket, and a gate controlling said pocket and said bin andpositivelycontrolling the discharge of materlal from both said pocket and said binduring a single movement.

Q'VThe combination with a bin, of a return pocket opening from thebottom thereof and comprising a receptacle with surextending above theopening from said bin, a gate opening the bottom of said pocket anddischarging material from said pocket while material is in said bin andmeans controlling the flow from said bin to saidlgate.

3. The combination with a bin, of a return pocket therefor comprising av-receptacle. with surrounding and upwardly extending walls adapted toreceive and retain material from abov" agpomm'on outlet for said pocketand saidin, a gate for controllin the flow from said bin to said outlet,an asecond gate independent of said first positively-controlling bothsaid mg a single movement.

Ail The combination with a bin, of a retherefor, of a downwardlyextending bagging pipe communicating directly with both said pocket andsaid bin,

fend a gate movable across said pip: and dismaterial from said poc etinad (margin the material fromsaid bin.

vaiice o The combination with a bin, of a re-' turn pocket therefor, acommon downwardly opening bagging pipe discharging material flow fromsaid chute to said pipe, and a. hori- I zontally movable gate forcontrolling the flow to said pipe from both the pocket and the bin. I

7. In a baggingpipe, the combination with a bin having an outlet, of areturn pocket having an outlet alongside of the outlet of said bin, anda gate sliding across both of said outlets to controltbe dischargefromsaid bin and said pocket..'

8. In a bagging pipe, the combination with a bin having an outlet, of areturn pocket having an outlet alongside of the outlet of said bin, anadjustable partition between said bin and said pocket, and a gatesliding across both of said outlets to control the discharge from saidbin and said pocket.

9. The combination with a bin and areturn pocket opening therefrom, of amain outlet gate the return pocket at one movement, and an auxiliaryadjustable partition controlling the. rate discharge of the bin.

In testimony whereof I aiiix my signature in presence of two Witnesses.
